Abstract

The invention provides a ceramic interior wall tile for construction produced by alkaline land luvial soil and a production process thereof, using the alkaline land luvial soil as a main raw material. The ceramic interior wall tile comprises the following compositions in percentage by mass: 40 to 48 percent of luvial soil, 12 to 15 percent of aedelforsite, 18 to 22 percent of kaolinite, 12 to 15 percent of diopside, 3 to 7 percent of Jilin soil, and 3 to 9 percent of talc. The ceramic interior wall tile prepared by the compositions has large mechanical strength, good thermal stability and low water absorption rate, has each technical index in accordance with national standard, and opens a new path in comprehensively developing and treating the alkaline land.

Description

Technical field: [0001] The invention relates to a ceramic inner wall brick for building and its production process, in particular, to a ceramic inner wall brick for building using saline-alkali deposit soil and its production process. Background technique: [0002] The ceramic industry is a resource-based industry. my country is a big country with natural mineral ceramic raw material resources, but it is not a country rich in various high-quality ceramic raw materials. The annual consumption of natural mineral ceramic raw materials is more than 100 million tons, consuming natural mineral ceramic raw material resources. The amount is huge, and natural mineral ceramic raw materials are non-renewable resources. Without the support of sufficient natural mineral ceramic raw material resources, the sustainable development of the ceramic industry cannot be realized. For example, after a hundred years of production in Tangshan ceramics industry, the high-quality ceramic raw materia...
